Two battery’s being charged?

[phatdaddy]

i think step is talking about the ACR switches, they direct the charge to the lowest battery. No matter which battery the switch is turned to.

I have 2 1000 MCA batteries hooked in parallel with a single on\off switch for the motor.

Alternator charges both. When using 110 vt charger, i hook to neg on one battery and positive on the other
